If the given pair of polygons are similar, then find the value of $x, y$ and $z$.

If the given pair of polygons are similar, then find the value of $x, y$ and $z$.

If the given pair of polygons are similar, then find the value of $x, y$ and $z$.

The lengths of the sides of a quadrilateral are $4 \mathrm{cm}, 6 \mathrm{cm}, 6 \mathrm{cm}$ and $8 \mathrm{cm}$. The lengths of the sides of another quadrilateral, which is similar to the first quadrilateral, are $6 \mathrm{cm}, 9 \mathrm{cm}, 9 \mathrm{cm}$ and $12 \mathrm{cm}$. What is the scale factor? (The second quadrilateral from the first quadrilateral). Write the answer in improper fraction.
